This Day in History
April 20, 1902 Marie Curie discovers radium

Madame Curie established many firsts as a woman of science. She was the first woman to attend the Royal Institution in London, the first to hold a professorship at the Sorbonne, and the first woman to be a member of The French Academy. If this was not enough, she was the first woman to win the Nobel Prize, and then the first person to win it twice. With her husband Pierre Curie and Henri Becquerel, she received her first Nobel in Physics for studies of radioactivity. Her patient experiments had been inspired by a previous discovery of radioactive X-Rays. She discovered that such radioactivity could be found in polonium and radium, elements that would form the basis for nuclear energy. In isolating those elements, she earned her 2nd Nobel in Chemistry.
